ROCKING-CHAIR.

SPECIFICATION forming part of Letters Patent No. 585,422, dated June 29,1.897.

Application filed November 27, 1896. Serial No. 613,502. (No model.)

To a/ZZ whom it may concern: l

Be it known that I, WILLIAM M. BOENNING, a citizen of the United States,and a resident of Port Vashington, in the county of Ozaukee and State ofWisconsin, have invented certain new and useful Improvements in Rocking-Ohairs; and I do hereby declare that the following is a full, clear, andexact description thereof.

My invention has for its object to provide a simple economical knockdownrockin g-chairg and it consists in certain peculiarities of constructionand combination of parts hereinafter set forth with reference to theaccompanying drawings and subsequently claimed.

Figure l of the drawings represents a partlysectional view of the majorportion of a rocking-chair constructed according to my invention; andFig. 2, a plan view illustrating the base and rocker mechanism of thechair, parts of this rocker mechanism being broken.

Referring by letter to the drawings, A A represent a pair of parallelbars set on edge and joined by intermediate rounds h to constitute thebase of my improved rocking chair. Pivotally connected to each side barof the base, near the extremities o f the same, are the lower ends ofrods B O, that cross each other and have their upper ends likewiseconnected to the side bars D of a seat-frame, the latter being supportedby said rods at the desired elevation clear of said base.

The parallel pair of rods B are shown connected bya round c, and roundsd e are shown connecting the other parallel pair of rods O, these latterrods being of greater length than those aforesaid for the purposehereinafter specified. The rods O are shown as arranged to come insideof the ones B, and the round c, connecting the outer rods, is in thedownward path of the others to serve as a stop for the same.

As herein shown, a spiral spring E may have hook-end connection undertension with the rounds c e, and resistance of the spring is thereforeproportionate to the degree of tilt that may be imparted to theseat-frame in either direction. Consequently there is always a tendencyof the movable parts toward their normal position herein shown.

The rods O are made longer than the ones B in order to obtain normalrearward tilt of the chair-seat,and the base extends far enough in rearof said seat t-o compensate for any tendency of the chair tovtopplebackward.

The rods B O are preferably of wood and their pivots of metal, thoseshown being engaged with corresponding sockets in the side bars of thebase and seat-frame. As herein fully illustrated, the pivots may beextremities of shouldered arms extending from metal sleeves F in drivingiit on ends of rods B O, and these sleeves are provided with aperturesfor stay-nails g, driven into said rods.

The pivotal connection of the crossed rods with the base and seat-framevinsures easy rocking action of the latter, the spring under tensionoperating to prevent sudden movement in either direction, therebyovercoming "the sensitiveness that otherwise exists.

In view of what has been shown and describedit is evident that the chairmay be readily knocked down and the parts packed in comparatively smallcompass for storage and shipment.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

l. A rockin g-chaircomprising a seat-frame, a base extended in rear ofthe seat-frame, and crossed rods in pairs pivotally connected to saidseat-frame and base to support the former, the rods of the pairconnecting the rear portion of the base with the aforesaid seatframebeing longer than those of the other pair.

2. A rocking-chair comprising a seat-frame, a base extended in rear ofthe seat-frame, crossed rods in pairs pivotally connected to saidseat-frame and base to support the former, the rods of the pairconnecting the rear portion of the base with. the aforesaid seatframebeing longer than those of the other pair, and a round uniting the shortrods arranged in the downward path of the long rods.

3. A rockin g-chair comprising a seat-frame, a base extended in rear ofthe seat-frame, crossed rods in pairs pivotally connected to saidseat-frame and base to support the former, the rods of the pairconnecting the rear IOO portion of the base with the aforesaidseatington,in the eonntyof Ozaukee and State of frame being longer thanthose of the other isconsirnin the presence of two Witnesses.
